     Ultrasonic Type (Liquid Level Indicator) LU Series

     

         ►Features  
    Obstacles in the tank are recognized as digital images. Measurement in a detection area narrowed down more than ever before is enabled by cutting unnecessary noise and filtering the output adequately.
    • It has become possible to perform difficult measurement in a narrow tank in a specific detection area.
    • Settings can be made easily using the push button and LCD.
    • Inch, cm, or % can be selected for the LCD display.
    • The transmitter can be used for various purposes thanks to the PVDF with excellent corrosion resistance.
    • The meter can be operated with ease thanks to the fail-safe function.

          ►Operating Principles

     

    The ultrasonic wave transmitted from the sensor reflects on the liquid surface, and the propagation time until the reflected wave is received by the sensor again is converted into the distance to the liquid surface and then output.
